Decision making in the prisoner's dilemma game: The effect of exit on cooperation and social welfare

The prisoner's dilemma game is a mixed‐motive game that offers two players the simultaneous choice between a cooperative and a defective alternative. An often neglected aspect of such a binary‐choice game, however, is that in many real‐life encounters, people can choose not only to cooperate or defect, but they also have a third option: to exit the social dilemma. Although in the literature a consensus has emerged that the addition of an exit opportunity benefits cooperation, there is only scant research into its effect on social welfare. In order to allow a direct comparison of cooperation rates and welfare levels across binary‐choice and trinary‐choice games, in this study, we used a design in which the same participants played similar games with and without an exit option (i.e., a within‐subjects design), and this in a range of structural variations. The findings of our study indicated that the aggregated outcome of both players is generally lower in games with an exit option than in games without an exit option. Moreover, our results showed that the efficiency of the exit option strongly depends on the specific outcome structure of the game (in terms of its endowment size, (a)symmetry, and level of noncorrespondence). In the discussion, it is argued that the implementation of an exit option as a strategy to increase social welfare should be critically assessed.     

The effect of decision timing on the willingness to costly reward cooperation and punish noncooperation: Sanctioning the past,the present,or the future

Numerous studies have demonstrated that sanctions can promote cooperation. However, it is important to know not only that sanctions can work but also under what conditions people are actually willing to sanction cooperation positively (i.e., reward) or noncooperation negatively (i.e., punish). In this article, we demonstrate that people use sanctions less often and sanction more mildly when they decide about sanctioning before (instead of after) the occurrence of others' (non)cooperation (Experiments 1 and 2), regardless of whether they decide directly afterwards or after a time delay (Experiment 2). Moreover, we reveal that beforehand (as compared with afterwards) people have not yet formed clear sanctioning preferences (Experiment 3). These findings corroborate our reasoning that the decision environment beforehand induces nonconsequential reasoning and thereby hampers people's willingness to sanction. We discuss the theoretical, methodological, and practical implications of our work.     

IN DEFENSE OF PUBLICS: PROJECTION,BIAS, AND CULTURAL NARRATIVES IN SCIENCE AND RELIGION DEBATES

John H. Evans's recent book Morals Not Knowledge is a timely argument to recognize broader social and cultural factors that might impact what U.S. religious publics think about the relationship between science and religion and their attitudes toward science and/or religion. While Evans's focus is primarily on what can be classed as moral issues, this response argues that there are other factors that sit within neither the older epistemic conflict model approach nor a moral conflict model approach that also merit further investigation. There is a significant need for further research that examines the social, psychological, (geo)political, and broader cultural factors shaping people's social identities in relation to science and religion debates. When undertaking such research, we need to be wary of creating a binary between scholarly and public space discourse. Social scientific research in this field should be led by public perceptions, attitudes, and views, not by concepts or frameworks that we project onto them.     

Does Cooperation in the Laboratory Reflect the Operation of a Broad Trait?

The Dictator Game, a face valid measure of altruism, and the Trust Game, a face valid measure of trust and trustworthiness, are among the most widely used behavioural measures in human cooperation research. Researchers have observed considerable covariation among these and other economic games, leading them to assert that there exists a general human propensity to cooperate that varies in strength across individuals and manifests itself across a variety of social settings. To formalize this hypothesis, we created an S‐1 bifactor model using 276 participants' Dictator Game and Trust Game decisions. The general factor had significant, moderate associations with self‐reported and peer‐reported altruism, trust, and trustworthiness. Thus, the positive covariation among economic games is not reducible to the games' shared situational features. Two hundred participants returned for a second session. The general factor based on Dictator Game and Trust Game decisions from this session did not significantly predict self‐reported and peer‐reported cooperation, suggesting that experience with economic games causes them to measure different traits from those that are reflected in self‐assessments and peer‐assessments of cooperativeness. © 2018 European Association of Personality Psychology     

Between the sea and the shore: mediating the Nine Emperor Gods Festival in Singapore

The Chinese diaspora brought tablets and effigies of their Taoist gods with them when they migrated to Southeast Asia. Temples in the region hold annual festivals to evoke this passage from the sea to the shore, assisted by makeshift sets, props, and generators with floodlights. In this article, I examine the durational performances of the Nine Emperor Gods Festival in Singapore, which consist of people and deities moving in processions. What does it mean to perform spirituality between the sea and the shore? What happens when this coastline is constantly redrawn with land reclamation? There is a mobile imagery described here: technological media transport yet circumscribe the spiritual to the material stage onshore as devotees invite the deities to land. The spiritual is eventually pulled back, leaving behind its residue (ashes, footprints on the sand, talismans) as the deities depart. Spirituality performed along the coast through technological mediation reveals the contemporary nature of these religious practices.     

Context-based variations in EFL teachers’ reflection: the case of public schools versus private institutes in Iran

The aim of the present study was twofold: examining the effect of contextual differences on the degree of English as a foreign language (EFL) teachers’ involvement in reflection and exploring context-related factors that may help/hinder the reflection process. A mixed-methods quantitative-qualitative procedure was adopted. Eighty-five Iranian EFL teachers (41 teaching in public schools and 44 working in private language institutes) completed the English-language teaching reflection inventory developed by Akbari, Behzadpour, and Dadvand (2010 Akbari, R., Behzadpoor, F., &; Dadvand, B. (2010). Development of english language teaching reflection inventory. System, 38, 211–227.10.1016/j.system.2010.03.003[Crossref], [Web of Science ®] , [Google Scholar]), with 10 of the participants attending a follow-up interview too. The results of multiple sets of independent samples t-tests showed that teachers in the private sector reported significantly more active involvement in lower levels of reflection (i.e. practical, cognitive, and affective reflection), while no measurable difference was detected between the two groups in terms of higher levels of reflection (i.e. metacognitive and critical reflection). Analysis of the interview data further revealed that teachers’ involvement in reflection was influenced by five main context-specific factors namely, knowledge of reflection, institutional demands, teachers’ attitude toward teaching, availability of resources, and collegial support. The implications of the findings for educational policymakers and teacher educators were discussed and suggestions were provided for future research.     

A tale of two processes: On Joseph Henrich’s the secret of our success: How culture is driving human evolution,domesticating our species,and making us smarter

We situate Henrich’s book in the larger research tradition of which it is a part and show how he presents a wide array of recent psychological, physiological, and neurological data as supporting the view that two related but distinct processes have shaped human nature and made us unique: cumulative cultural evolution and culture-driven genetic evolution. We briefly sketch out several ways philosophers might fruitfully engage with this view and note some implications it may have for current philosophic debates in moral and political theory and over the nature of extended cognition. We end by noting how Henrich’s view of the source of cultural design and innovation, and the prominence of place he gives to the extended process of cultural evolution, cuts against a cluster of broad but common views about human minds, recasting putative bugs as features and indicating that many of the distinctive features of our individual minds evolved to allow them to be effective cogs in the larger, more productive cultural machine.
